Quick Answer
TikTok auto-plays content on mute. Over 80% of users scroll with sound off. Captions are essential for TikTok Live engagement. StreamTranslate adds real-time subtitles via OBS browser source, baked directly into your TikTok Live video.
Why TikTok Live Needs Captions
TikTok is a mute-first platform. The majority of users scroll with sound off, only enabling audio for content that catches their attention visually. For TikTok Live streams, this means:
- Most viewers entering your live stream are on mute initially
- Captions are the first thing muted viewers read — they determine whether someone stays
- Translated captions reach TikTok's massive international audience
- TikTok's algorithm favors streams with higher retention — captions improve retention
